3-{4-[6-(1-Hydroxymethyl-propylamino)-2-oxo-3-propyl-3,7-dihydro-2H-purin-8-yl]-bicyclo[2.2.2]oct-1-yl}-propionic acid methyl ester (30 mg) was dissolved in 1 mL of SOCl2 and stirred under reflux for 15 min. The reaction mixture was then cooled to rt and concentrated under reduced pressure. The resulting residue was dissolved in a solution containing 1 mL of water, 0.5 mL of MeOH, and 0.1 mL of 10% aq. NaOH. The reaction mixture was stirred at rt for 30 min. It was then acidified to pH 2 with dilute 1 N HCl and concentrated. The resulting crude product was purified by preparative HPLC to afford the titled compound.
